Left-wingers at Google are engaged in a relentless effort to demonetize Breitbart News from its AdSense platform and are linking advertising clients to the anti-Breitbart, far-left pressure group Sleeping Giants.

Breitbart News has obtained a screenshot (withheld to protect our source) that shows Google ad account manager Aidan Wilks advising another company – a client of Google’s – that advertising on Breitbart may impact their “brand safety.”

In the screenshot, Wilks can be seen linking Google’s client to the website of Sleeping Giants, a far-left organization that has repeatedly targeted Breitbart and other conservative-leaning news sites with false claims of racism and bigotry.

According to multiple sources, leftist employees sent an open letter to Google’s management calling on them to demonetize Breitbart, which amassed over seven hundred supporters across the company.

The feature was abruptly canceled after a Daily Caller report revealed that it almost exclusively targeted conservative news sites, including Breitbart News, often by incorrectly attributing claims to their stories.
